Letters PatentNo. 108,384, dated October 18, 1870.

IMPROVEMENT iN-cuLTlvA-roRs.

The Schedule referred to in ,these Letters Patent and making part of the-same.

To all whom it may concern.'

Be it known that I, Cromo P, N citron, of Prairie City, in the county ot' Jasper and State of Iowa-have invented a new and useful Improvement in Oultivators; and Ido hereby declare that the following is a tull, clear, and exact'description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a vertical longitudinal section of my improved cultivator, taken through the line a' x, fig. 2.

. tion and effective in operation and It consists in the construction and combination of various parts of the machine, as hereinafter more fully described. y

A are two bars, which are placed parallel with each other, the one above and the other below the tongue B,'to which they are pivoted bya bolt passin gA through their middle points, as shown in fig. 2.

To and between the ends of the two bars A is pivoted the forward part of the side bars O, the rear parts of which are pivoted to the ends of the crossbar D, the middle part of which is pivoted to the rear end ofthe tongue B, the loose-jointed -frame A Gl) thus serving as a double-tree.

'W'ith the side bars of the frame A (l D are connected runners E, to carry the machine as may be desii-ed.

Fare the plow-beams, to the rear parts of which are attached handles G, plow-standards H, plows I,

and braces J, in the ordinary manner.

To the sides of theforward ends of the plow-beams F are securely bolted the plates K, which are made in the form and manner shown in the drawing; that is to say, upon the upper edges of their forward partsv `are formed upwardly-projecting parts, which are made thicker than the bodies of the plates K, or have inwardly-projecting flanges formed upon their upper or curved edges, vas shown in figs. 3 and 4. To and between the lower parts of the forward ends of the plates K is pivoted a bleek, L, by a bolt passing through the said plates and block, as shown in fio. 3.4

all are rods, having heads formed upon their lower ends, which rods passl up vertically through holes inthe blocks L.

The forward ends ofthe upwardly-projecting parts ofthe plates K are connected with a bolt, k', as'

shown in figs. 1,2, 3, and 4, so that they may be drawn toward each other, to bear against the rods M `and to take up the wear. This construction allows the rear parts ofthe plow-beams to have a free vertical and lateral movement, and at the same-time will always hold the plowsin a verticalposition.

` The rods-M pass upv through the forward ends of the slots in the claspsjorv blocks N,whch are .placed V and lit between the bars A, and which are securedin place by the wedge-keys O, driven into the rear ends vof the slots in thesaidblocks, at the rear edges ofthe ,bars A.

In .the forward' 'edges of the bars A are formed a number of notches to receive the rods M, so that the' said rods may be held securely in place, and at the same time kept in a vertical position. This construction enablesthe ends ofthe plow-beams to be readily and quickly raised and lowered, and moved toward and from each other, whenrequired.

To the rear ends of the side bars G are att-ached rods P, -having hooks formed Iupon their lower ends,

upon which the brace-rods ofthe plow-standards may be hooked, to hold lthe plows away from the ground when passingr from place to place.

. Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The arrangement of the runners E, plows F H K,

rods M, blocks L, wedges O, tongue B, andl jointed l double-tree frame A O D, as shown and described,

for the purpose setforth.
